@remi1doc. Yes, you have to post them somewhere for them to be accessible (sometimes I post to an Items group instead of to my feed first). And if someone has posted an item, it means anyone has permission to automatically use it.
@remi1doc. I also don't want to steal others' items in their collections if they're not up for public use . So I don't know what others can use or not . ๐ I'm still uneducated about most the features here I guess! Lol
